Isn't first { $_ } @array the same as $array[0]? (except where $array[0] contains a "false" value.)

sub lowercase {
  return ( wantarray ) ? map { lc } @_ : lc $_[0];
}

Is your intended use of 'first' really just looking for elements that contain some non-false value (because that's what it does)? If so:

return ( wantarray ) ? map { lc } @_ : lc( first { $_ } @_ );

ie, no need to 'lc' the entire @_ if you are only returning one. Find the one you want, 'lc' it, and return that.
